Penjelasan dengan langkah-langkah:
LP = 2pl + 2pt + 2lt
= 2(12×3) + 2(12×20) + 2(3×20)
= 2(36) + 2(240) + 2(60)
= 72 + 480 + 120
= 552 + 120
= 672 cm²
I hope this help :)

Jawab:
Lbalok = 2 × ( pl + pt + lt )
L = 2 × ( 12 × 3 ) + ( 12 × 20 ) + ( 3 × 20 )
L = 2 × ( 36 + 240 + 60 )
L = 2 × 336
L = 672 cm²
